In October 2006, artist Carsten Höller installed five large slides in the Turbine Hall of Tate Modern in London. The visitors of the museum had the chance to hurtle down these silver slides and experience a feeling of letting go and losing control. The longest slide was 55,5 meters long and dropped 26,5 meters from level five of the building to the Turbine Hall floor.
